I have a Stingray Ray 5 and I love the sound but when I plug into a SansAmp bass driver or the cheapest Behringer BDI21 tube driver, I really hate my sound. I notice that my active bass doesn't sound good like my pasive basses but I really want to use my stingray to play. It doesn't sound like a tube and sound distorted all the time. I put the bass flat, the amp flat, close the drive knob but doesn't work at all Any other device that can emulate tube amp than cost under $200?
